Hi,
I am trying to come up with a Reverse Proxy using HttpCore, however came across
some difficulties and hope someone here could point me into the right direction.
Basically I am having a servlet putting all of the received headers into a
BasicHttpRequest instance, which it then sends with sendRequestHeaders(). So
far this would work, however once I try to get the response by
receiveResponseHeader() it simply stalls at
AbstractSessionInputBuffer.fillBuffer() upon reading from instream. This would
make me believe the server hasnt yet sent any response - most probably because
it didnt yet receive the full request. I could confirm the latter partly when I
tried to send the request manually (via the socket's output stream) as I could
then receive the response successfully. Furthermore it also seems to work by
not using sendRequestHeader() and receiveResponseHeader() but instead a
HttpRequestExecutor.
My assumption would be that something about sending the request is not right
yet, but I couldnt say what. Below is an a bit trimmed down version, did I miss
something?
HttpRequest req=null;
req=new BasicHttpRequest(request.getMethod(), "path-to-connect-to");
for (Enumeration<String> e=request.getHeaderNames();
e.hasMoreElements(); )
{
String header=e.nextElement();
for (Enumeration<String> _e=request.getHeaders(header);
_e.hasMoreElements(); )
req.addHeader(header, _e.nextElement());
}
Socket socket=new Socket('hostname', 80);
DefaultHttpClientConnection con=new DefaultHttpClientConnection();
con.bind(socket, new BasicHttpParams());
con.sendRequestHeader(req);
HttpResponse resp=con.receiveResponseHeader();
response.setStatus(resp.getStatusLine().getStatusCode());
Thanks for any help,
Alexander
